PACKING- PRISMA'1IC ARTICLES.

Application filed January 11, 1926, Serial No. 80,536, and in Austria April 10, 1925.

The object of this invention\ is a method of packing prismatic articles, especially lumps ofsugar for use ,in caf-s or other kinds of foodstuffs, 5 the consumer himself and, until then, be protected from unhygienic handling on the part of other persons. At the same time, as a result of itspcculiarly extensive surface, the packing affords room for various kinds of texts, pictures, advertisements or the like, which become visible when the packing is opened. Y

Such packing should, on the one hand, he made of light material, such as thin paper which may be easily folded but on the other hand, it should afford sufficient protection against unintentional tearing';in short. it should be tough enough and allow of simple and rapid unwrapping.

To this end, the packing which is the object of thisinvention consists 'of a sheet of 7 paper which has two wings of any desired length, connected by a bar. These wings are folded brcadthwise towards the bar, reinforcedif desired by side flaps laid one upon the other, so that a figure resembling a squat I is formed. The bar several layers of paper.- The bar of the I- shaped figure is folded about three faces of the prism, while the two wings now laid one upon the other on the fourth face of the prism arefolded around the ends" to meet again and lie one upon the other on the opposite faoeof the; object.

packing according to the invention. Fig. 1 shows the sheet of paper laid flat, while the Figures 2, 3, 4, 5 and 6 illustrate the folding of the sheet at the various stages of packing. Figs. 7 and 8 show an alternative form of the object of the invention.-

The sheet in Fig. 1 is stampedin the form of two wings, a and b, of any desired length, which are joined together bymeans of a bar 0, and with incisions d to make the bar flaps f, and has in the upper right-hand cornera strip of edging (7. So that the wrapping may be performed in the correct manner. the

the surfaces to be covered are previously drawn or printed uponbothsides ,of the Q sheet, and these lines also mark out fields for advertisement inscriptions.

and must be folde breadthwise' at the so that they may be opened by and rippe itself is made out of The drawings illustrate examples of the f crease lines h, corresponding to the size of To repare the wrapping, the twowings, a

bar 0 (Fig; 2), While the two flaps f are laid I one upon the other over the remaining'bar c. TlllS folding forms an I-shaped figure (Fig. 3), the bar of'which is wrapped around three faces of the prism 71; (Fig. 4.), whilethe two w.ngs of this I-shapedfigure are causedto he upon one another on the fourth'side of the prism to be wrapped up,-then they are (label) n. Thereby the strip of edging g covers the steps made by the folds and therefore prevents the individual folds from being stuck together by the seal.

To open the tape m is grasped by one end d off, tearing away with it the seal a, so that the wrapping is opened and the sugarmay be taken out. At the same time, the whole of the folded wrapping is opened, so that the advertisements, or the like placed upon the wings, a and b may be read. According to the alternative form illustrated in Figs. 7 and 8 the sheet is so made thatthe use of the tape to break the seal is superfluous. In this form, instead of the narrow strip ofedging g at the corner of the wing a, there is a larger flap i, which is separated'from the main sheet by incisions r'. This flap is folded along the creases h into a narrow strip which protrudes over the it that it is a good substitute for the tape,

for the purpose of opening the wrapping. In this case the sealfis broken by means of the folded strip.- Thisform of carrying out the invention has the advantage of greater simplicity of manipulation and lower cost on account of the absence of the tape.

What I claim is t 1. A packing, for-prismatic-articles such as lumps of sugar and the like, comprising an I-shaped sheet of flexible material the bar or stem portion of which is dimensioned to cover three faces of the article to be wrapped and the two wings capable of being superposed on the. fourth face of said article and extending 'over the ends of the latter to over llll g i I 1,636,528

lap oneanother on the face opposite said fourth face. i

2. A wrapper for prismatic articles such as lumps of sugar and the like, comprising a sheet formed of two wings connected by a bar and folded brcadthwise towards the latter, said bar having reinforcing side flaps superposed thereon, said wings and bar when folded "forming an I-shaped figure of superposed layers, the bar being proportioned to cover three side faces of the article to be wra'ppedand the two wings superposed on the fourth side face of said article and extending over the ends of the latter overlapping one another on the face opposite said fourth face.

3. A wrapper for vprismatic articles such on the fourth side face of said article and extending over the ends of the latter overlapping one another on the face opposite said fourth face, one of said wings having a protruding strip arranged to extend beyond the folded ortion thereof.

4. A wrapperor prismatic articles such as lumps of sugar and the like, comprising a sheet formed of two wings connected by a bar and folded breadthwise towards the latter, said bar having reinforcing sidefla-pssuperposed thereon, said wings and bar when folded forming an I-shaped figure of superposed layers, the bar being proportioned to cover three side faces of the article to be wrapped and the two wings superposed on the fourth side face of said article and extending over the ends of the latter overlapping one another on the face opposite said fourth face, a seal connecting the overlapping wings, one of said wings having a strip extending late-rally and longitudinally beyond the side and end thereof, said strip being folded into aplurality of layers and protruding beyond the ends of the package forming a means to'break said seal.

In testimony that I claim the foregoing as my invention, I have signed my name.
